T0 at whom it may concern.-

Beit known that I, VOLNEYW. MASON, J R., a citizen of the United States, residing at Hyde Park, in the county of Norfolk and State of Massachusetts, have invented a new and Improved Vise for Milling-Machines, Planers, &c., of which the following is a specification.

This improved vise is intended particularly for use in connection with milling machines, but there are other machines to which it may be applied, such as planers; and I propose to use it in connection with any machine where it will be of service.

Vises for milling machines as ordinarily constructed have two jaws or clamps, one having a limited movement with relation to the other, and the capacity of the vise is confined to the very limited movement of this movable In my improvement, the capacity of the vise is very greatly enhanced as is also the length and nicety of the adjustment of the parts upon the bed of the milling or other machine.

In the accompanying drawings, in which similar letters of reference indicate like parts, Figure 1 is a perspective view of my improved device secured to the bed of the milling machine. Fig. 2 is a central longitudinal vertical section of the same. Fig. 3 is a detail in plan and horizontal section, illustrating the operation of the holder for irregular pieces.

A represents portions of the frame of the milling machine and A the table secured thereto, upon which table is the bed B of the vise. This bed is provided with, say, three,

shape shown, and, say, four transverse intersecting parallel grooves B of substantially the same shape.

0 represents one of the jaws or clamps of the Vise, and may be considered as that which takes the place of the stationary jaw in the ordinary vise. tionary, but is secured by bolts D and nuts D to the bed, the heads of said bolts lying in the wings of the grooves B and the nuts serving to secure the jaws O in any desired position, whether near to or remote from the right hand edge of the bed. This aw is provided with the face-plate O secured thereto It is not however, in fact, staby the screws C". E is the other jaw of the the bed by meansof the bolts I and nuts I in exactly the same manner as the jaws C E. A screw or bolt K extends into a correspondingly threaded horizontal opening L in the rear end of the jaw E, said screw being provided with a smooth portion K which extends through a smooth horizontal bore in the sliding block H, and is held therein by a shoulder K and the head K It will readily be seen that the limitof the range or capacity of this vise is the limit of the length of the bed to which the jaws are secured, inasmuch as the jaw O can be secured at the extreme right hand end of the bed, the block H at the extreme left hand end, and the jawE drawn by the bolt Kclose to the block H. The adjustments consist, first, of the movement of the jaw O longitudinally on the bed, second, of the movement of the block H on the bed, third, the movement of the jaw E with relation to the block H produced by the bolt K, and fourth, the movement of the jawE allowed by the elongated slots 6.

P is a holder orsupplemental jaw intended to accommodate irregular or non-rectangular pieces or articles. This holder P which may be of anydesired thickness as shown in the three figures, has a rearward extension or knuckle P which extends horizontally into a concavity or groove R in the plate E (see Fig. 3). An irregular piece clamped between the jaws E and 0 would therefore cause the holder or supplemental jaw P to turn or swing horizontally, as shown bybroken lines in Fig. 3, and conform to the angle of one side of the piece being held. A flange or shoulder P" provides a corner for holding the piece and preventing it from slipping out horizontally, and as the groove B does not extend quite to the top of the plate E, an

overhanging lip R is produced, which prevents the piece from jumping vertically.

The jaws G E and block H can be readily removed at any time if desired, by means of 5 the transverse grooves B Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a vise, the combination of the jaw E :0 provided with the vertical groove B, said groove or recess extending into the face of the jaw below its upper surface but not breaking the face line of said jaw at its upper edge, and the swinging holder or supplemen- 15 tal jaw P provided with the knuckle P for
